  Log Message:
  -----------
  [Image Redux] Generated images (e.g. cross-fade()) in a CSS content property 
don't have correct decoding mode or interpolation quality set
https://bugs.webkit.org/show_bug.cgi?id=326087

Reviewed by Alan Baradlay.

Use the Style::Image paths for decoding mode and interpolation quality for 
RenderImage drawing to make
generated images used with the CSS `content` property work correctly.

Also implements interpolationQualityForImageDraw for Style::CrossfadeImage to 
make it pick appropriate
values and making the `image-rendering` apply correctly (which is tested in the 
new layout test).
